Australia does not possess weapons of mass destruction, although it has participated in extensive research into nuclear, biological and chemical weapons in the past.
Australia chairs the Australia Group, an informal grouping of countries that seek to minimise the risk of assisting chemical and biological weapon proliferation. All states participating in the Australia Group are parties to the Chemical Weapons Convention and the Biological Weapons Convention, and strongly support efforts under those Conventions to rid the world of chemical and biological weapons. [1] As with chemical and biological weapons, Australia does not possess nuclear weapons and is not seeking to develop them.
Australia has advanced research programs in immunology, microbiology and genetic engineering that support an industry providing vaccines for domestic use and export. [2] It also has an extensive wine industry and produces microorganisms on an industrial scale to support other industries including agriculture, food technology and brewing. The dual-use nature of these facilities mean that Australia, like any country with advanced biotechnological industries, could easily produce biological warfare agents. The Australian Centre for Disease Preparedness in Geelong, Victoria is researching the Ebola virus. [3] The Australian Microbial Resources Research Network lists 37 culture collections, many of which hold samples of pathogenic organisms for legitimate research purposes. [4]
In the wake of the Japanese advance through South East Asia during World War II, the secretary of the Australian Department of Defence, Frederick Shedden, wrote to virologist Macfarlane Burnet on 24 December 1946 and invited him to attend a meeting of top military officers to discuss biological warfare. [5]
In September 1947, Burnet was invited to join the chemical and biological warfare subcommittee of the New Weapons and Equipment Development Committee and subsequently prepared a secret report titled "Note on War from a Biological Angle". [6] In 1951 the subcommittee recommended that "a panel reporting to the chemical and biological warfare subcommittee should be authorised to report on the offensive potentiality of biological agents likely to be effective against the local food supplies of South-East Asia and Indonesia". [5]
The activities of the chemical and biological warfare subcommittee were scaled back soon after, as Prime Minister Robert Menzies was more interested in trying to acquire nuclear weapons. [5] Australia signed the Biological Weapons Convention on 10 April 1972 and deposited a certificate of ratification on 5 October 1977. [7]
Australia conducted extensive research into chemical weapons during World War II. Although Australia has never produced chemical weapons, it did stockpile chemical weapons sourced from the United States and Britain. [8] Chemical weapons known to have been stockpiled included mustard gas, phosgene, lewisite, adamsite and CN gas.
Some of the stockpiled weapons in the form of mortar and artillery shells, aerial bombs and bulk agents were sent to New Guinea for potential use against Japanese tunnel complexes. [8] No actual use of the weapons was made although there were many trials using 'live' chemical weapons (such as shown in the adjacent picture).
After World War II, the chemical weapons were disposed of by burning, venting (for phosgene) or by dumping at sea. Some 21,030 tons of chemical weapons were dumped in the seas off Australia near Brisbane, Sydney and Melbourne. This has been covered in a Defence report by Geoff Plunkett. A complete history of Australia's involvement with chemical weapons – titled Chemical Warfare in Australia – has been published in book form by the Army History Unit (Defence Department) in 2013 (2nd Edn) Again it is authored by Geoff Plunkett .
A stockpile of 1,000 pound phosgene bombs was discovered at Embi Airfield, Papua in 1970 and disposed of by Australian Army personnel, and, up to 1990, drums of mustard gas were still being discovered in the bush where they had been tested. [8] Another stockpile of chemical weapons was discovered at Maxwelton, Queensland in 1989. [5] Australia signed the Chemical Weapons Convention in January 1993 and ratified it with the Chemical Weapons (Prohibition) Act in 1994. [8]
Australia does not currently have nuclear weapons and has never had its own nuclear weapons, although several federal governments have investigated the idea and conducted research into the question. [9] Australia investigated acquiring tactical nuclear weapons from the United Kingdom or the United States as early as 1956 when Athol Townley, Minister for Air, wrote to Philip McBride, Minister for Defence, recommending the acquisition of tactical nuclear weapons to arm Australia's English Electric Canberra bombers and CAC Sabre fighters. [10] [11] [12]
Air Chief Marshal Frederick Scherger and Minister for Air Athol Townley supported acquiring nuclear weapons, both for international prestige and because of the small size of the country's military. While Scherger's British and American counterparts were encouraging, the Macmillan and Eisenhower governments were not. Prime Minister Robert Menzies' government decided that domestic production would be too difficult due to cost and international politics. [13]
Australia hosted British nuclear testing in Monte Bello Islands (Operation Hurricane), Emu Field and Maralinga between 1952 and 1957. Maralinga was developed as a joint facility with a shared funding arrangement. [14] During the 1950s, Australia participated in the development of the Blue Streak missile, a Medium-range ballistic missile (MRBM) intended for delivery of a nuclear warhead.
The Australian HIFAR nuclear reactor at Lucas Heights, Sydney, operated from 1958 to 2006 and has now been replaced by the OPAL reactor in 2006. The new reactor is designed to use low-enriched uranium fuel and an open pool light water system. [15]
Australia has substantial deposits of uranium which account for 30% of the world's known reserves. [16] Until 1996 government policy restricted exploitation of uranium deposits to three established mines. A fourth site at Four Mile uranium mine was approved in July 2009. [17] Current policy is to develop the export potential of Australia's uranium industry by allowing mining and export of uranium under strict international agreements designed to prevent nuclear proliferation. [18]
Although the RAAF continued to occasionally investigate obtaining nuclear weapons during the 1960s, [13] Australia signed the Nuclear Non-Proliferation Treaty on 27 February 1970 and ratified the treaty on 23 January 1973. [19] Sir Philip Baxter first head of the Australian Atomic Energy Commission (AAEC), now the Australian Nuclear Science and Technology Organisation (ANSTO) and first Vice Chancellor of the University of New South Wales openly advocated Australia acquiring a weapons grade plutonium stockpile and thus nuclear weapons. [20]
During the 1970s and 1980s, ANSTO scientists developed centrifuge enrichment technology, claimed to be comparable with the commercial URENCO centrifuge technology of the time. Such technology, if deployed on an industrial scale, would have been capable in principle of producing highly enriched uranium for nuclear weapons. The research lost government funding in the mid-1980s. [21]
A commercial-scale enrichment plant would also be capable of producing sufficient highly enriched uranium for a nuclear weapons program. An Australian company has been actively developing a novel process for uranium enrichment, Separation of Isotopes by Laser Excitation (SILEX). [22]
The Prime Minister of Australia, John Howard, began a study in 2006 into the issues surrounding an increase in Australia's uranium usage. [23] Amongst the topics of the study were a domestic uranium enrichment plant for supplying low-enriched fuel for nuclear power reactors, either domestic or foreign.
In 2019, Hugh White, a military strategist, called for Australia to have nuclear weapons. [24] [25] [26] [27]
Like virtually every other developed nation and most larger developing nations, Australia has weapons systems which could be used to deliver nuclear weapons to its neighbours, if nuclear weapons were developed. [28] The Royal Australian Air Force has 63 F-35A Lightning II strike fighters (72 total on order) and 24 F/A-18F Super Hornet strike fighters.
Australia previously operated the Douglas A-4 Skyhawk ground-attack aircraft and the English Electric Canberra and General Dynamics F-111C bombers, which were theoretically capable of delivering nuclear weapons, and F-111G tactical bombers which converted from United States Air Force FB-111A strategic nuclear bombers. 75 F/A-18A/B Hornets were also operated until their retirement in 2021. Prior to the delivery of the F-111C, Australia briefly operated the McDonnell Douglas F-4E leased from the United States Air Force, standard Block 43/44 models capable of delivering nuclear weapons.
As part of Air Staff Requirement (Operational Requirement/Air) 36 for bomber aircraft in the 1950s, the Royal Australian Air Force specified a requirement for "an offensive tactical strike capability" and "strategic defence of Australia" with targets "as far north as the Kra Peninsula". The bomber was required to have a range of not less than 4,000 nautical miles (7,400 km) and be capable of carrying at least 20,000 pounds (9,100 kg) of conventional bombs or one BLUE DANUBE nuclear weapon (which had been air dropped at Maralinga on 11 October 1956). [29] Locally manufactured versions of the Avro Vulcan or Handley Page Victor nuclear bombers were some of the options considered.
In 2010 Lowy Institute poll asked If some of Australia’s near neighbours were to begin to develop nuclear weapons, would you then be personally in favour or against Australia also developing nuclear weapons?
It found that 16% were in favour (4% strongly in favour, 12% somewhat in favour) while 84% were against (63% strongly against, 21% somewhat against). [30]
In 2022, the Lowy Institute performed another poll on Australians’ support for nuclear weapons. It found 11% strongly in favour and 25% somewhat in favour, for a total of 36% in favour (an increase from the 2010 poll), while 24% were somewhat against and 39% were strongly against acquiring nuclear weapons. [31]
The Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT, is an international treaty intended to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy, and to further the goal of achieving nuclear disarmament. Between 1965 and 1968, the treaty was negotiated by the Eighteen Nation Committee on Disarmament, a United Nations-sponsored organization based in Geneva, Switzerland. A central premise of the NPT is that NPT non-nuclear-weapon states agree not to acquire nuclear weapons and the NPT nuclear-weapon states in exchange agree to share the benefits of peaceful nuclear technology.
Nuclear proliferation is the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to nations not recognized as "Nuclear Weapon States" by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT. Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare, de-stabilize international or regional relations, or infringe upon the national sovereignty of nation states.
Enriched uranium is a type of uranium in which the percent composition of uranium-235 has been increased through the process of isotope separation. Naturally occurring uranium is composed of three major isotopes: uranium-238, uranium-235, and uranium-234. 235U is the only nuclide existing in nature that is fissile with thermal neutrons.
Chemical warfare (CW) involves using the toxic properties of chemical substances as weapons. This type of warfare is distinct from nuclear warfare, biological warfare and radiological warfare, which together make up CBRN, the military acronym for chemical, biological, radiological, and nuclear, all of which are considered "weapons of mass destruction" (WMDs), a term that contrasts with conventional weapons.
A weapon of mass destruction (WMD) is a biological, chemical, radiological, nuclear, or any other weapon that can kill or significantly harm many people or cause great damage to artificial structures, natural structures, or the biosphere. The scope and usage of the term has evolved and been disputed, often signifying more politically than technically. Originally coined in reference to aerial bombing with chemical explosives during World War II, it has later come to refer to large-scale weaponry of warfare-related technologies, such as biological, chemical, radiological, or nuclear warfare.
The United States is known to have possessed three types of weapons of mass destruction: nuclear, chemical, and biological weapons. The U.S. is the only country to have used nuclear weapons on another country, when it detonated two atomic bombs over two Japanese cities of Hiroshima and Nagasaki during World War II. It had secretly developed the earliest form of the atomic weapon during the 1940s under the title "Manhattan Project". The United States pioneered the development of both the nuclear fission and hydrogen bombs. It was the world's first and only nuclear power for four years, from 1945 until 1949, when the Soviet Union produced its own nuclear weapon. The United States has the second-largest number of nuclear weapons in the world, after the Russian Federation.
The United Kingdom possesses, or has possessed, a variety of weapons of mass destruction, including nuclear, biological, and chemical weapons. The United Kingdom is one of the five official nuclear weapon states under the Treaty on the Non-Proliferation of Nuclear Weapons. The UK renounced the use of chemical and biological weapons in 1956 and subsequently destroyed its general stocks.
France is one of the five "Nuclear Weapons States" under the Treaty on the Non-Proliferation of Nuclear Weapons, but is not known to possess or develop any chemical or biological weapons. France is the only member of the European Union to possess independent (non-NATO) nuclear weapons. France was the fourth country to test an independently developed nuclear weapon, doing so in 1960 under the government of Charles de Gaulle. The French military is currently thought to retain a weapons stockpile of around 300 operational (deployed) nuclear warheads, making it the fourth-largest in the world, speaking in terms of warheads, not megatons. The weapons are part of the country's Force de dissuasion, developed in the late 1950s and 1960s to give France the ability to distance itself from NATO while having a means of nuclear deterrence under sovereign control.
The People's Republic of China has developed and possesses weapons of mass destruction, including chemical and nuclear weapons. The first of China's nuclear weapons tests took place in 1964, and its first hydrogen bomb test occurred in 1966 at Lop Nur. Tests continued until 1996, when the country signed the Comprehensive Nuclear-Test-Ban Treaty (CTBT), but did not ratify it. China acceded to the Biological Weapons Convention (BWC) in 1984 and ratified the Chemical Weapons Convention (CWC) in 1997.
Israel is believed to possess weapons of mass destruction, and to be one of four nuclear-armed countries not recognized as a Nuclear Weapons State by the Non-Proliferation Treaty (NPT). The US Congress Office of Technology Assessment has recorded Israel as a country generally reported as having undeclared chemical warfare capabilities, and an offensive biological warfare program. Officially, Israel neither confirms nor denies possessing nuclear weapons.
Canada has not officially maintained and possessed weapons of mass destruction since 1984 and, as of 1998, has signed treaties repudiating possession of them. Canada ratified the Geneva Protocol in 1930 and the Nuclear Non-proliferation Treaty in 1970.
Pakistan is one of nine states that possess nuclear weapons. Pakistan began developing nuclear weapons in January 1972 under Prime Minister Zulfikar Ali Bhutto, who delegated the program to the Chairman of the Pakistan Atomic Energy Commission (PAEC) Munir Ahmad Khan with a commitment to having the device ready by the end of 1976. Since PAEC, which consisted of over twenty laboratories and projects under reactor physicist Munir Ahmad Khan, was falling behind schedule and having considerable difficulty producing fissile material, Abdul Qadeer Khan, a metallurgist working on centrifuge enrichment for Urenco, joined the program at the behest of the Bhutto administration by the end of 1974. Producing fissile material was pivotal to the Kahuta Project's success and thus to Pakistan obtaining the capability to detonate a nuclear weapon by the end of 1984.
From the 1960s to the 1990s, South Africa pursued research into weapons of mass destruction, including nuclear, biological, and chemical weapons under the apartheid government. South Africa’s nuclear weapons doctrine was designed for political leverage rather than actual battlefield use, specifically to induce the United States of America to intervene in any regional conflicts between South Africa and the Soviet Union or its proxies. To achieve a minimum credible deterrence, a total of six nuclear weapons were covertly assembled by the late 1980s.
Iran is not known to currently possess weapons of mass destruction (WMD) and has signed treaties repudiating the possession of WMD including the Biological Weapons Convention, the Chemical Weapons Convention, and the Non-Proliferation Treaty (NPT). Iran has first-hand knowledge of WMD effects—over 100,000 Iranian troops and civilians were victims of chemical weapons during the 1980s Iran–Iraq War.
Although Germany has the technical capability to produce weapons of mass destruction (WMD), since World War II it has refrained from producing those weapons. However, Germany participates in the NATO nuclear weapons sharing arrangements and trains for delivering United States nuclear weapons. Officially, 20 US-nuclear weapons are stationed in Büchel, Germany. It could be more or fewer, but the exact number of the weapons is a state secret.
In 1952, the United Kingdom became the third country to develop and test nuclear weapons, and is one of the five nuclear-weapon states under the Treaty on the Non-Proliferation of Nuclear Weapons.
Libya pursued programs to develop or acquire weapons of mass destruction from when Muammar Gaddafi seized control of Libya in 1969 until he announced on 19 December 2003 that Libya would voluntarily eliminate all materials, equipment and programs that could lead to internationally proscribed weapons. This included weapons of mass destruction and long-range ballistic missiles.
During the late 1940s and 1950s, Sweden had programs for both nuclear and chemical weapons. During the first decades of the Cold War, a nuclear weapons program was active.
The United States chemical weapons program began in 1917 during World War I with the creation of the U.S. Army's Gas Service Section and ended 73 years later in 1990 with the country's practical adoption of the Chemical Weapons Convention. Destruction of stockpiled chemical weapons began in 1986 and was completed on July 7, 2023. The U.S. Army Medical Research Institute of Chemical Defense (USAMRICD), at Aberdeen Proving Ground, Maryland, continues to operate.
Egypt had a history of weapons of mass destruction and used chemical weapons during the North Yemen Civil War. Although it has signed the Nuclear Non-Proliferation Treaty, it still remains one of only four countries not to ratify the Chemical Weapons Convention and has not ratified the Biological Weapons Convention.
